NAME

       pam_strerror - return string describing PAM error code

SYNOPSIS

       #include <security/pam_appl.h>

       const char *pam_strerror(pam_handle_t *pamh, int errnum);

DESCRIPTION

       The pam_strerror function returns a pointer to a string describing the error code passed in the argument errnum, possibly using the
       LC_MESSAGES part of the current locale to select the appropriate language. This string must not be modified by the application. No library
       function will modify this string.

RETURN VALUES

       This function returns always a pointer to a string.

NAME

       pam_putenv - set or change PAM environment variable

SYNOPSIS

       #include <security/pam_appl.h>

       int pam_putenv(pam_handle_t *pamh, const char *name_value);

DESCRIPTION

       The pam_putenv function is used to add or change the value of PAM environment variables as associated with the pamh handle.

       The pamh argument is an authentication handle obtained by a prior call to pam_start(). The name_value argument is a single NUL terminated
       string of one of the following forms:

       NAME=value of variable
	   In this case the environment variable of the given NAME is set to the indicated value: value of variable. If this variable is already
	   known, it is overwritten. Otherwise it is added to the PAM environment.

       NAME=
	   This function sets the variable to an empty value. It is listed separately to indicate that this is the correct way to achieve such a
	   setting.

       NAME
	   Without an '=' the pam_putenv() function will delete the corresponding variable from the PAM environment.

       pam_putenv() operates on a copy of name_value, which means in contrast to putenv(3), the application is responsible to free the data.

RETURN VALUES

       PAM_PERM_DENIED
	   Argument name_value given is a NULL pointer.

       PAM_BAD_ITEM
	   Variable requested (for deletion) is not currently set.

       PAM_ABORT
	   The pamh handle is corrupt.

       PAM_BUF_ERR
	   Memory buffer error.

       PAM_SUCCESS
	   The environment variable was successfully updated.
